I'm not sure it'll get better or worse. I imagine it won't change drastically either way. They'll probably get a slightly more old school feel and scale back from the over the top "sports entertainment", but not a lot.
WWE is a machine that can coast for a very long time doing what they are doing now. Coke Boy laid out the blue print over the last 30 years. All Steph & HHH have to do is keep doing what they've been doing.
This. It's a proven money-making formula, Steph and HHH are very familiar with it, they've been part of the machine for a long time, and they know it works. It will be largely the same going forward, with the odd subtle change and maybe little old-school experiments that HHH might want to try.
Maybe the comedy bits will be slightly less corny because I always had the feeling that Vince's weird/sick sense of humor dominates WWE "comedy", but I guess it wouldn't be shocking if Steph finds that same kind of shyt funny.
